ABSTRACT:
A ball catch coupling for releasably connecting two parts which permits relative rotation of the parts in the connected conditions as an annular section carried on one of the parts with a number of uniformly disposed bores at a periphery thereof, balls respectively received and rotatable in each of the bores, a closed resilient ring surrounding the balls, an annular groove in the annular section which receives the ring and permits limited axial displacement and free rotation thereof within said groove, and the other part to be connected having an annular groove which at least partially receives the ring and the balls when the two parts are connected. The limited displacement and free rotation of the ring with respect to the annular section permits engagement and disengagement to be undertaken particularly easily and with low wear.
